based on what i see i would say its a standard production eclipse model. looks like a maple top that is fairly thick, mahogany back, older emgs, and a floyd rose instead of a sinclair. Based upon that my best guess would place it from 1990 to 1994. I would bet a penny on 92 or 93 if I had to narrow it down, but really it is all just an educated guess you can try emailing esp support, i am told they can sometimes identify the old models with picture and the serial number.
